In-game Cursor Getting Stuck
I don't know what causes it, but it happens every single game I play Renekton. Every so often during gameplay (and multiple times per game), my cursor will get stuck on the icon that is shown when you ping. I lose the ability to click on the map to view that spot and to ping (of any type). It usually lasts for 30 seconds to 2 minutes, on average, but it is highly annoying. I haven't had issues with it playing any other champion lately, so I figure it must be Renekton.
I play on a Macbook Pro, if that helps.
I don't know what else you need, tbh, but it's definitely a bug and rather heavily impacts gameplay at times.
